Character Density Selection

(PCL Level III)

Standard-density print, high-density print, and high-speed draft printing can
be specified using the following escape sequences:

Primary Selection

ESC(s0Q

Select Standard-Density (12 x 9 dot matrix, 120 x 72 dpi) for the
primary font

ESC(s1Q

Select High-Density (18 x 12 dot matrix, 180 x 96 dpi) for the
primary font

ESC(s-1Q Select High-speed Draft Printing (12 x 6 dot matrix, 120 x 48 dpi)

for the primary font

Secondary Selection

ESC)s0Q

Select Standard-Density (12 x 9 dot matrix, 120 x 72 dpi) for the
secondary font

ESC)s1Q

Select High-Density (18 x 12 dot matrix, 180 x 96 dpi) for the
secondary font

ESC)s-1Q Select High-speed Draft Printing (12 x 6 dot matrix, 120 x 48 dpi)

for the secondary font

The default density is that of the default font specified from the control panel.
If the symbol set selected is not available in the requested density, the printer
will print blank space. However, OCR-A, OCR-B, and Postal Barcodes force
density changes to ensure scanability.

When draft printing is selected, the printer prints less dots vertically (5 dots).
This reduction in dots results in an increase in print speed of up to 30%.

For example, to cue high-density ASCII:

ESC(0UESC(s1Q

To cue high-speed draft with Roman Extension:

ESC(0EESC(s-1Q

The following table lists all the Symbol Sets available to the PCL II Emulation.
Each Symbol Set is followed by its selection Code, and the Densities(Pitches)
that it is available in. With the exception of OCR-A and OCR-B, selecting a
symbol set in a Density combination not listed in the chart below will result in
spaces being printed in place of the desired character.
